Electric Vehicles

The Best Part of an EV Is When You’re Not Driving

That enormous battery can do a lot more than propel your car down the road.

Many new cars and trucks come with modes to optimize driving. Anyone who’s watched an episode of Top Gear has seen the hosts extoll the virtues of sport mode, which makes steering tighter and more responsive, or off-road mode, which allows a 4X4 to better cross muddy terrain.

Electric vehicles have their own performance modes, like Tesla’s “launch control” that sends the Model S screaming off the starting line. But some of the most interesting things an electric car can do happen when it’s sitting still. Because the giant battery along the bottom of an EV can do a lot more than propel the car down the road, EV-makers have realized they can use this reserve of electricity to create quality-of-life features that wouldn’t be possible in gasoline cars.


There used to be a set of no-nos when it came to sitting in the car. Running the air conditioner, listening to music, or leaving the headlights on without the motor running would tax the boxy 12-volt battery found under the hood. Overdo it and you might need to talk a stranger into a jump-start, something I learned the hard way when I was a pre-teen and depleted the battery in my parents’ Pontiac minivan waiting for them to escape a meeting.

Cars got better about this issue as the years went by, but electric vehicles nearly negate the problem entirely. Consider the modern sin of leaving one’s pets behind. States like California have laws against leaving an animal unattended in a hot car, and for good reason — without ventilation, a vehicle interior can get even hotter than the outside air. Combustion cars can’t (or shouldn’t) keep the air conditioner on without also running the engine, which prevents you from keeping the pooch nice and cool.

Not so in the EV age. Rivian and Tesla both have pet modes that will use the battery’s electricity to run climate control while you run into Walgreens while Walter the terrier stays behind. Both brands display a cheery cartoon dog on the large center touchscreen, alongside a message to would-be Good Samaritans that the cabin is holding a pleasing and pleasant temperature.

Pet modes come with safeguards. They can’t be used if the battery is too low, for example, to prevent a scenario in which the car runs out of juice and can no longer cool the dog. Still, they can’t guard against the fact that this new technology runs against a societal stigma against leaving pets in the car. (I keep paper signs in my Model 3 that read “AC ON, DOG IS FINE” to dissuade passersby from breaking a window or calling the authorities.)

Humankind benefits from EV climate features, too. Leaving the heat or AC on indefinitely bleeds a few miles of range from the battery, but doesn’t endanger your ability to get the car started again. You could even sleep in the comfort of a climate-controlled room on wheels (or park cranky kids in front of Encanto on the touchscreen). Tesla offers Camp Mode for this very purpose, promising that an entire night uses only about 10 percent of the battery. Rivian’s is especially high-tech: It tweaks the truck's suspension to keep it level on uneven ground, and allows owners to shine their headlights to illuminate the campsite, a definite battery-killer in a combustion car.


These applications are mere extensions of the familiar, giving traditional car accessories a lot more staying power. The transformative potential of driving a battery on wheels would be the ability to use that electricity supply for, well, anything you want.

The technical name is bidirectional, or two-way, charging. The Ford F-150 Lightning includes this feature, and its advertising touts that the electric truck can plug into your home to provide days of backup power in the event of a blackout. Tesla’s initial round of Cybertruck marketing proclaimed that the steel beast would become the mobile heart of a jobsite, with power tools running on battery power thanks to an array of outlets on the vehicle’s exterior.

Two-way charging makes an EV more technically complex, since the direct current (DC) power the car uses would need to be transformed back into alternating current (AC) to run other applications. But the possibilities are enticing for the electric vehicle owner. EVs that remain plugged in while not in use could feed energy back onto the electrical grid, just as homes with solar panels can pass on excess energy. Such a setup could help avoid blackouts by creating an alternative source of stored electricity — not to mention generate income for EV owners who are technically selling power back to the grid.

It is coming, if slowly. Tesla, having resisted bidirectional, said this spring that it would adopt the technology within a couple of years. Other automakers have introduced some limited versions of it.

Someday soon, then, your car, flashlight, and backup generator may be one and the same.

A Big Battery Relief in New York

And more of the week’s top news around project fights.

The United States.

1. Suffolk County, New York – Rarely do I get to say battery fire fears can be quelched but we have a very good example brewing in the Empire State.

  • On September 11, New York state regulators did a Friday News Dump: The Department of Environmental Conservation confirmed a large PFAS pollution site in East Hampton was explicitly tied to fighting a battery storage site fire. The investigation began after PFAS chemicals, known as “forever chemicals,” were detected in drinking water wells.
  • Investigators will still have to produce a final report, but in their bulletin confirming the pollution source, the agency said it is now working with state energy and fire officials to avoid a specific chemical fire suppression system identified as a potential culprit known as Novec 1230. “The investigation points to the fire suppression system, not battery storage, as a [PFAS] source,” the bulletin states, adding this system wasn’t used in other recent fires at BESS facilities.This defuses what was poised to be a new PR problem for the battery storage sector in a state where local moratoria and restrictive ordinances have become increasingly common.

2. Loudon County, Virginia – I can’t believe it: Data Center Alley is going to enact a moratorium.

The Case for a Data Center Dividend

A conversation with Sam Lyman of the Bitcoin Policy Institute.

This week’s conversation is with Sam Lyman, head of research at the Bitcoin Policy Institute. Originally focused on cryptocurrency, Lyman’s organization has expanded to policy and messaging development around data centers, most notably providing research many AI boosters cite to claim foreign influence is driving opposition to new hyperscale projects. Last week, the think tank released a new report calling for a novel solution to the data center permitting bottleneck: direct cash payments from data center projects to individuals involved with building them, as well as residents nearby facilities once they’re operating.

I reached out to BPI and asked for a chat with Lyman about the data center dividend proposal. I also tried to get to the bottom of where this increasingly relevant think tank stands on the general idea of a national data center law. The conversation was immensely informative. So here it is, in a lightly abridged and edited format.

The Bipartisan Buddies With a Plan to Fix Transmission

With a permitting deal seemingly on the horizon, Republican Gabe Evans and Democrat Scott Peters may be about to see their partnership pay off.

The fate of permitting reform legislation that could smooth the way to all kinds of new and improved energy infrastructure — including transmission lines and renewables — is currently hostage to opaque discussions between Senate committee chairs. Rhode Island Senator Sheldon Whitehouse, the Democratic ranking member of the Senate Environment and Public Works Committee, told a Rhode Island business group earlier this week that “we’re actually in a pretty good place on permitting reform,” and that there was “maybe another week of negotiations.” Whitehouse’s Republican counterpart on the EPW committee, West Virginia Senator Shelly Moore-Capito, told Semafor on Friday that any bill has “got to pop out of here in the next 48 hours.”

If that’s going to happen, it will be because Republicans and Democrats have decided it’s worth it to get along. Any deal will eventually have to be voted on by the House, which has already produced several bills on a bipartisan basis, and even passed one — the SPEED Act — late last year.
